Kingdom Hearts HD 2.8: Final Chapter Prologue is out now on the PS4 and it contains a short prologue to the upcoming Kingdom Hearts 3 called ‘A Fragmentary Passage’ featuring Aqua from Kingdom Hearts: Birth By Sleep.

If you play through Kingdom Hearts 0.2 the first time, you might have the chance to repeat it again in order to fight a secret boss battle. This boss battle is only unlocked once you discover 12 Zodiac chests that are scattered around the world map. These chests can be located by following the video guide below.

Once you have located the required 12 Zodiac Chests, you can head to the mirror world to unlock a secret boss battle. This is a cool new addition to the short prologue that adds some replay value for it.

Kingdom Hearts HD 2.8: Final Chapter Prologue features a remaster of Kingdom Hearts: Dream Drop Distance, a movie explaining the backstory of the Foreteller with Kingdom Hearts X Back Cover, and a prologue to Kingdom Hearts 3 that focuses on Aqua’s time in the World of Darkness called Kingdom Hearts 0.2 Birth by Sleep: A Fragmentary Passage.

Kingdom Hearts HD 2.8: Final Chapter Prologue is available now for the PS4.
